RECIPROCATING COMPRESSOR, DRIVE DEVICE OF RECIPROCATING COMPRESSOR AND CONTROL MEDHOD OF RECIPROCATING COMPRESSOR

摘要

The present invention, in particular, the efficiency is improved in the general load, the operating frequency that efficiency is improved by controlling the frequency of the input power source so as to follow the resonant frequency is varied according to the load variation of the compressor according to a driving device and a control method of a reciprocating compressor It will have to be. Reciprocating compressor according to the present invention comprises an inverter for controlling the input power frequency, the resonance frequency of the reciprocating compressor is set within 60 to 90% range of the commercial power source frequency, input to the power supply frequency corresponds to a resonant frequency by an inverter It will be set to the frequency. Further, the present invention is to a control unit for controlling the input power frequency of the reciprocating compressor operation frequency so as to follow the resonance frequency changes with the reciprocating compressor work.
